I work for a retailer and we certainly do not use a third party insurer, and I don't see why any other consumer retailer selling inexpensive merchandise would use insurance. It is priced in.

In fact, we use RFID tracking to know when goods are stolen, not to save money, not to catch shoplifters, but to improve inventory management and ensure that we get a replacement item on the shelf to avoid losing sales.

Highly doubt it. You can't insure the inevitable.
